Spaced Repetition is a technique for helping you remember things in the long term, in an efficient way.

If you paid someone to stand next to you and shout a fact at you, every waking minute of the day, for six weeks, you may remember the fact they shouted. But would it have been an efficient use of time? Certainly not.

On the futility of memory

Yes, suddenly I saw it clearly: most people deceive themselves with a pair of faiths: they believe in eternal memory (of people, things, deeds, nations) and in redressibility (of deeds, mistakes, sins, wrongs). Both are false faiths. In reality the opposite is true: everything will be forgotten and nothing will be redressed. The task of obtaining redress (by vengeance or by forgiveness) will be taken over by forgetting. No one will redress the wrongs that have been done, but all wrongs will be forgotten.
